Multiple-day severe weather outbreak to threaten central US late this week

March 22,2017, 2:45:15PM,EDT

Severe thunderstorms and the risk to lives and property will ramp up
late this week over parts of the central United States as the first in a
series of spring storms arrives.
There is the potential for a significant severe weather outbreak spanning Thursday afternoon through Saturday.

The overall severe storm threat will
cover the full spectrum of dangerous weather ranging from wind gusts
topping 60 mph and large hail to frequent lightning strikes and isolated
flash flooding.
"Given the time of the year, there will likely be
at least a few tornadoes in the strongest storms from Thursday into
Saturday," according to AccuWeather Senior Meteorologist Henry
Margusity.RELATED:The difference between tornado watches and warnings6 life-threatening tornado myths debunked5 essential safety steps to take before severe weather hitsWhat is Tornado Alley? AccuWeather Severe Weather Center
"A combination of record warmth,
surging moisture, a strong storm and shifting winds at different levels
of the atmosphere, known as wind shear, will set the stage for severe
weather beginning over the southern and central Plains," according to
AccuWeather Senior Meteorologist Joe Lundberg.
The first storms
are likely to erupt over the High Plains from western Texas to western
and central Nebraska, near the boundary between dry air to the west and
moist air to the east on Thursday afternoon.

"It is possible that the worst period
in terms of the intensity of the storms will be from late Thursday to
the first part of Thursday night," according to AccuWeather Lead Storm
Warning Meteorologist Eddie Walker.
Into Thursday night, the
threat of severe weather will extend Scottsbluff and North Platte,
Nebraska, to Lamar, Colorado; Dodge City, Kansas; and Amarillo and
Lubbock, Texas.
A lull in the thunderstorm activity during Friday
morning and midday may spare some areas the worst of the storms from
Topeka and Wichita, Kansas, to Oklahoma City, and Dallas, Austin and San
Antonio, Texas. However, storms are likely to ramp up just east of
these areas during Friday afternoon.

During Friday evening, the risk of
violent storms will extend from eastern Kansas and western Missouri to
northeastern Texas and western Louisiana.
The dangerous and potentially damaging storms will press toward the Mississippi River during the overnight hours on Friday.
There will be the potential for severe thunderstorms over the lower Mississippi Valley and Delta region on Saturday.

People are urged to monitor the forecast and severe weather bulletins closely as they are issued.
Additional
rounds of severe weather are likely to follow over many of the same
areas later this weekend and into next week. A long parade of storms
will continue to roll in from the Pacific Ocean, move across the
Intermountain West then reorganize over the Plains.
